Should Bandwidth Throttling (BWM) increase Latency on a Sonicwall TZ190?
Posted on 2009-02-23
I have implemented BWM (bandwidth management) on our Sonicwall TZ190's to limit the amount of traffic over the WAN. I need WAN traffic limited so that the RDP traffic going over the VPN is not effected with high latency. However, it appears that with BWM enabled and active it does increase the latency, between 100-250ms. Without the BWM and WAN traffic sucking up all available bandwidth the latency climbs to over 600ms.
So, BWM does help and works. However, is it anyone else's experience with BWM that latency would climb like this and should be considered normal?
